FIG. 1 illustrates a charging system 10, e.g., for charging electronicdevices such as a phone, a tablet, or a laptop (not shown). The chargingsystem 10 includes multiple blocks or portions or segments 18 connectedto one another in an end-to-end configuration. In the illustratedembodiment, each segment 18 includes multiple charging ports 22. Forexample, the charging system 10 of FIG. 1A includes three segments 18,and each segment 18 includes four ports 22 (e.g., a port for receiving aUSB-type connector). In other embodiments, the charging system 10 mayinclude fewer or more segments 18. In addition, as shown in FIG. 1B,each of the segments 18 may include fewer or more ports 22, and/or mayinclude a different type of port (e.g., a wireless charging port 26).The segments 18 can be combined in various ways to achieve a desiredconfiguration.

As shown in FIG. 2 , each segment 18 includes a first end 30 and asecond end 34. The first end 30 includes a first connector 38 and thesecond end 34 includes a second connector 42. Each first connector 38 isconfigured to be connected for electrical communication with the secondconnector 42 of an adjacent segment 18. In the illustrated embodiment,the first end 30 of each segment 18 is formed as an upper portion andthe second end 34 of each segment 18 is formed as a lower portion; thefirst connector 38 is position on a lower surface of the upper portion,while the second connector 42 is positioned on an upper surface of thelower portion. In the illustrated embodiment, the upper portion of thefirst end 30 engages a lower portion of the second end 34 of an adjacentsegment 18 in an overlapping configuration. In other embodiments, thesegments 18 may be interconnected in a different manner.

In some embodiments, each connector 38, 42 includes a protrusionengaging a corresponding feature (e.g., an opening) on the associatedportion of the adjacent segment 18. The protrusions and openings mayalternate between the connectors 38, 42 (e.g., each connector 38, 42 mayinclude a protrusion and an opening, such that the protrusion engagesthe opening of the other connector). In other embodiments, theconnectors 38, 42 may include protrusions that engage each otherdirectly. In still other embodiments, the connectors 38, 42 may beformed in a different manner, and/or the segments may be interconnectedin a different manner. The electrical connections between the segments18 can be made via an interlocking mechanical coupling rather than awired connection. The coupling may be threaded, magnetic, spring, clip,interference, or some combination thereof. One of the connectors 38, 42of an end segment 18 of the charging system 10 is connected to a powerinput, e.g., a plug 50 in electrical communication with a power source.

As shown in FIG. 3 , the charging system 10 may include a power bus 70configured to receive an AC input or a DC input. For an AC input (FIG.3A), the charging system 10 includes a rectifier 74 for converting theinput current to DC current. For a DC input (FIG. 3B), the currentpasses through a regulator 78. In each case, the current flowing to theports 22 (and therefore to the electronic devices) may be controlled bya controller 82. The charging system 10 may connect to a standard AC orDC mains 86 or an alternative power supply or inverter. The power busconnection may be made by a threaded, spring contact, or connectorsystem, or some combination thereof.

As shown in FIGS. 4A-4C, each segment 18 may include various numbers andtypes of ports 22. For example, as shown in FIG. 4A, a segment 18 mayinclude four ports 22 for receiving a USB-type connector. As shown inFIG. 4B, a segment 18 may include two ports 22 for receiving a USB-typeconnector. As shown in FIG. 4C, a segment 18 may include a wirelesscharging port 26. That is, the segments 18 can provide a variety offunctions. In addition, electronic communications can be included in oneor more segments 18 to transmit a signal (e.g., via Bluetooth, Wi-Fi,near-field communication, Ethernet, and/or an app). In some embodiments,the signal may indicate to external devices (e.g., a smartphone ortablet) the location of the charging system 10 and its status, forexample, that it is available for use. This system could assist users inlocating a nearby available charger and/or alert users when a port 22becomes available. This program could be implemented in various ways,including software beacons (not shown) running an operating system (e.g.iOS, Android, etc.).

In addition, a segment 18 may include a backup battery, as well as anenergy harvesting device (e.g., solar cell), either alone or incombination with the backup battery. One or more segments 18 may includean information display to provide the system status, the chargingstatus, or to provide space for advertisements. One or more segments 18may also include one or more light-emitting elements 90 (e.g., a lightemitting diode or LED—FIGS. 4A and 4C) for safety, aesthetics, or otherpurposes.

Because the segments 18 are interchangeable and can be linked togetherin communication with a common power bus 70, the charging system 10provides greater flexibility and serviceability, and can be more easilyupgraded. The modular nature of the segments 18 permits the system to beconfigured in various ways, and to include one or more segments 18,depending on the power bus capacity. In one embodiment, a maximum powerrating for each segment 18 including four ports 22 (e.g., FIG. 4A) iscalculated for a power consumption of 5 W for each port, correspondingto a total of 20 W. A maximum number of segments 18 connected in seriescould then be determined based on a target rating.

Each segment 18 is a pre-built assembly that may be formed from plastic,metal, resin, or some combination thereof, and may be assembled bythreaded, magnetic, clip, or interference connections, or somecombination thereof. Each segment 18 can be connected to other segments18 to provide a customizable charging system 10. The segments 18 maycommunicate with each other through the power bus 70, additionalconnections, or wireless methods.

The charging system 10 may be positioned adjacent a shelf 96. Forexample, for a charging system 10 mounted on a wall as shown in FIG. 1 ,the shelf 96 a may be positioned below the charging system 10 to supportthe device(s) to be charged. In other embodiments, the shelf 96 b (FIG.5 ) may be positioned adjacent seats 98 in a public environment such asan airport terminal or waiting area. In other embodiments, the chargingsystem 10 could be incorporated into other structures, such asbenchtops, armrests, etc.

The embodiments described above and illustrated in the figures arepresented by way of example only and are not intended as a limitationupon the concepts and principles presented herein. As such, it will beappreciated that variations and modifications exist within the scope andspirit of one or more independent aspects as described.
